editWeb tool executes a SPARQL query and saves the result to wikipage. SPARQL query and target page is defined in the link which opens the tool. After the tool is opened, the tool shows the link to query.wikidata.org where the query can be previewed. The user can execute the query, and tool will save the result to wikipage. After the save tool will show if the saving was successful and the link to the wikipage in Tabular Data format.

SELECT ?item
?itemLabel
(YEAR(?date) as ?year)
?population
WHERE
{
BIND(wd:Q33 as ?item)
?item p:P1082 ?populationStatement .
?populationStatement ps:P1082 ?population
; pq:P585 ?date .
SERVICE wikibase:label { bd:serviceParam wikibase:language "en" }
FILTER (YEAR(?date) >= 1960)
}
ORDER BY ?objectLabel ?year
- Open Query in the web interface
- Execute the query and get result in JSON format
Output
editThe result should be stored to Beta commons to the page defined in parameter wikipage
in Tabular Data format.
- Notes
- In the commons data namespace, stored data needs to be formatted to a two-dimensional array.
- Following datatypes should be handled when saving values as tabular data
- Float and integers = number
- Boolean = boolean
- any other = string
Sample for tabular data JSON
